MDD112B-N-040-N2M-130PB1

The Bosch Rexroth Indramat MDD112B-N-040-N2M-130PB1 is a high-performance servo motor in the MDD Synchronous Motors series engineered for precision automation. This permanent magnet synchronous motor integrates a multiturn encoder with digital servo feedback to ensure accurate position control and rapid response to dynamic load changes. It operates at a nominal speed of 4000 min⁻¹ and provides a continuous torque at standstill of 17.5 Nm, delivering robust performance in demanding industrial settings. The unit features an integrated blocking brake with a holding torque of 14.0 Nm for secure holding during emergency stops or power loss. Compact in design, the MDD112B-N-040-N2M-130PB1 combines efficient thermal management with rugged construction for reliable long-term operation.

Technical specifications of the MDD112B-N-040-N2M-130PB1 are engineered to exacting standards. The rotor’s moment of inertia measures 120 × 10⁻⁴ kg·m², contributing to a favorable torque-to-inertia ratio that enhances acceleration and deceleration profiles. Winding inductance is specified at 1.5 mH, optimizing current response and limiting electrical noise. The motor’s centering diameter of 130 mm and overall size code of 112 ensure compatibility with standard mounting arrangements, while the length code B denotes the housing variant. Balance class N, as defined by DIN VDE 0530, is achieved through precision mass distribution, and the shaft sealing ring protects against contamination and liquid ingress. Housing design standardization facilitates straightforward integration into existing machine frames.

Operational features emphasize durability and maintenance-free performance. The brushless design eliminates commutator wear, extending service intervals and reducing lifecycle cost. Bearings are pre-lubricated for up to 30 000 operating hours, supporting high radial loads without external maintenance. Integrated thermal sensors monitor stator winding temperatures, triggering protective measures to prevent overheating. The integrated multiturn absolute encoder combined with digital servo feedback enables closed-loop control with high resolution and repeatable startup without homing routines. The keyed output shaft, supplied without side B end, and the connector-type connection on Side B provide secure mechanical coupling and simplified electrical interfacing.

System integration with Bosch Rexroth digital drive controllers is seamless, leveraging built-in feedback protocols and parameterization tools for rapid commissioning. The MDD112B-N-040-N2M-130PB1 is ideally suited for applications in material handling, robotics, transfer systems, printing and packaging machinery, and precision machine tools. Its combination of high overload capacity, accurate feedback, and robust brake functionality supports advanced motion profiles and safety requirements. As part of the MDD Series of motors for digital drive controllers, this unit delivers the performance, reliability, and flexibility demanded by modern automated manufacturing environments.
